EN IEC 61788-24:2018

Superconductivity - Part 24: Critical current measurement - Retained critical current after double bending at room temperature of Ag-sheathed Bi-2223 superconducting wires

IEC 61788-24:2018 describes a test method for determining the retained critical current after double bending at room temperature of short and straight Ag- and/or Ag alloy-sheathed Bi-2223 superconducting wires that have the shape of a flat or square tape containing mono- or multicores of oxides. The wires can be laminated with copper alloy, stainless steel or Ni alloy tapes. The test method is intended for use with superconductors that have a critical current less than 300 A and an n-value larger than 5.

Supraconductivité - Partie 24: Mesurage du courant critique - Courant critique retenu après double flexion à température ambiante des fils supraconducteurs Bi-2223 avec gaine Ag

IEC 61788-24:2018 décrit une méthode d’essai permettant de déterminer le courant critique retenu après double flexion à température ambiante de fils supraconducteurs rectilignes courts Bi-2223 avec gaine Ag et/ou en alliage d’Ag, ayant la forme d’une bande plate ou carrée et contenant des noyaux simples ou plusieurs noyaux d’oxydes. Les fils peuvent être stratifiés avec des bandes en alliage de cuivre, en acier inoxydable ou en alliage de Ni. La méthode d’essai est destinée à être utilisée avec des supraconducteurs ayant un courant critique inférieur à 300 A et une valeur n supérieure à 5.

Superprevodnost - 24. del: Meritve kritičnega toka - Obdržani kritični tok po dvojnem upogibu posrebrenih Bi-2223 superprevodnih žic pri sobni temperaturi (IEC 61788-24:2018)

Ta del standarda IEC 61788 opisuje preskusno metodo za določanje obdržanega kritičnega toka
po dvojnem upogibu (pri sobni temperaturi) posrebrenih ali s srebrovo zlitino prevlečenih
Bi-2223 superprevodnih žic z obliko ravnega ali kvadratnega traku, ki vsebuje eno- ali
večjedrne okside. Žice so lahko laminirane s trakovi iz bakrene zlitine, nerjavnega jekla ali
nikljeve zlitine.
Preskusna metoda je namenjena za uporabo s superprevodniki, katerih kritični tok je manjši
od 300 A in n-vrednost večja od 5. Preskus za določanje obdržanega kritičnega toka
se izvede brez magnetnega polja, pri čemer je preskusni vzorec potopljen v odprto kopel
s tekočim dušikom.
